Hallo,
I got a Yokogawa WT333 power meter with /G5 option. There are 2 vis, fetch harmonics and fetch normal. The meter seems to have different registers that are then queried. Single values and multiple. So can I put the fetch harmonics and fetch normal in one vi, seems it switches the mode of the meter then. Plus it seems to take about 1.5 s to pull the values of the harmonics out. But I need to measure powers as well. Other option would be, the first values in the harmonics have current, phase angle and voltage, so I would have to calculate the rest.
cheers,
Steffen
